Abstract
In this test, ‘Jinzhu 100’ was used as the test material. The effects of different nitrogen and phosphorus fertilizers on maize yield index and quality index were studied through field experiments. Provide theoretical basis for Tianjin's big database of smart agriculture. Under N4P3 treatment, the number of maize rows, vane length and 100-grain weight were the highest. Under N3P2 treatment, maize grain yield was the highest. Under N3P3 treatment, the CP and starch content of maize grains were highest. Under N3P4 treatment, the starch content and CP of maize stems and leaves were the highest. Under N4P4 treatment, the ADF was highest in seeds and stem leaves. The content of NDF of seeds was the highest when treated with nitrogen fertilizer 300 kg/hm2 and phosphorus (P2O5) 75 kg/hm2. The content of NDF of stems leaves was highest under the treatment of nitrogen application of 300 kg/hm2 and phosphorus application amount (P2O5) of 112.50 kg/hm2. The rational application of different nitrogen and phosphorus fertilizers for different maizes is conducive to the improvement of its yield and quality.
